“…The minimum calcaneal lateral approach is 5 cm proximal and in line with the base of the fifth metatarsal to provide lifting the collapsed thalamic surface, followed by introduction of percutaneous K. wires and screws under roentgenographic guidance (Fig. 1) (13). Stabilization of the fracture is achieved following restoration of the thalamic surface with a steinmann nail, K. brooches or percutaneous screws.…”

Minimally invasive treatment and internal fixation vs. extended lateral approach in calcaneus fractures of thalamic interest

The extended lateral side approach is a common technique in the surgical treatment of calcaneal fractures, with thalamic collapse offering a good exposure of the fractured site; however, it can be burdened with complications due to soft tissue trauma. The present study aimed to compare patients treated with minimally invasive osteosynthesis through a minimum lateral approach and internal fixation with patients that were treated using internal fixation with an extended lateral side approach in cases of intra-articular calcaneal fractures with thalamic fracture. Patients were evaluated preoperatively and postoperatively by performing clinical and imagistic examinations, with radiography scans of the anterior-posterior calcaneal profile and computer tomography. Furthermore, preoperative and postoperative analyses of the Böhler angle on the radiological profile, complications and duration of the hospital admission for both groups were performed. There were 36 patients (39 calcaneal fractures) in group 1 and 24 patients (29 calcaneal fractures) in group 2. The results demonstrated no statistically significant differences in the preoperative (P=0.72) and postoperative (P=0.20) Böhler angle values. The postoperative Böhler angle average values were 26.9 in group 1 and 29.3 in group 2. A total of 11 patients were treated with Kirschner wires inserted in the calcaneus, and in 2/ll cases, one of the brooches registered a migration movement. There were no cases of material migration in the fractures that were stabilized by inserting Kirschner brooches up to the astragalus and cuboid bones. Taken together, the results of the present study demonstrated no significant differences in the Böhler angle values between the minimally invasive and open reduction techniques. However, the antibiotic therapy period, as well as the infection rate were lower in patients that were treated using the minimally invasive technique, suggesting that this technique was superior with respect to lower complication rates and improved functional results.
